Most are simplfied versions of the usual effect types. The fixed noise gate is a new palm slicer noise gate. And the Air Chorus has an additional Mix parameter, which allows to blend it into a Vintage Chorus.
what would be the parameter-settings of this effect to closest match the sound of the vintage chorus? (yes have read the v13 addendum)
Does the mix-parameter affect more than just "the mix" ie does it influence the depth or rate or another hidden parameter that might be found in a regular chorus?
